A Russian-Ukrainian crew that set sail in September on an historic expedition around the South and North Poles went missing in the Antarctic on Friday after encountering gale-force winds. A spokeswoman for the eight-person crew on board the 29-metre (97-foot) Scorpius sailboat said the team made its last radio contact on Monday night as it prepared for another treacherous leg of its journey in the South Shetlands. The mission website’s last entry said the Scorpius met gale-force winds on its way to Deception Island — a location popular with adventurers for its restless volcano.
